CPU card was a bit odd. It was 1986/1987 vintage and
appeared to have Z80000-series chips (yes, that has the right number of
zeros). I remember Zilog making a Z80000, but I don't know any details.
I think I have the Z80000 data sheets somewhere...
Ah yes, here we are, at least a Preliminary Product Specification
A ha ha ha ha ha ha . Of course !
As they say in France,Tony you are truly "incroyable" (incredible)
I am never failed to be blown away by 3 people on this M-L.
Tony, Allison, and Jason Pero. We are indeed fortunate.
Not to downplay the immense knowledge of all things TRS 80 and
master of the politically incorrect cryptic comment Ward Griffiths.
Or the immense knowledge of mini's of Tim Shippa As well as the
general guruhood of a goodly number of the members.
The archives of this newsgroup could be the base of a Masters course on

It appears to be a 32 bit CPU wit linear or segmented
addressing and
on-chip cache. One other thing is that the instruction set is an
binary-compatibile extension of the Z8000 instruction set. So probably
Zeus would run on it with few if any changes.
Was it Z8000-compatible? This particular machine
is labeled as a Zilog
asset, so there's a chance it includes goodies that didn't make it into
the real world.
I'd heard that the Z80,000 (Zilog always put the comma in) was either
never sold or only sold in prototype quantities. Sounds like you have
quite a find there...
